To all whom it may concern:

Be it known that 1, JOHN OLIPHANT Mc- KEAN, a citizen of the United States, and a resident of Westfield, in the county of Hampden and State of Massachusetts, have invented new and useful 1m rovements in Winding-Machines, of whic the following is a specification.

My invention relates to machines for Winding thread or the like upon a spool or coptube; and the object of my invention is to provide an improved machine of this class.

In my im roved winding-machine the co is supporte by a holder and rotated to Win the thread thereon, while the thread is laid onto the cop by a thread-guide carried by a traverser, to which it is frictionally connected so as to be movable toward and from the cop being wound. During the winding operation the frictional connection between the threadguide and traverser allows the thread-guide to yield away from the cop as the latter grows in diameter. caused by defective winding or a knot-will thrust the thread-guide more or less away from the cop, and the thread-guide will maintain that distant position until the cop grows sufficiently to rengage the thread-guide. In this way irregularities or protuberances on the surface of the cop being wound cannot cause irregular movements of the threadguide, which would result in irregular windin the best form of my invention the co holder is movable and comprises a s ind le carrying a power-transmitting wheel riven by a power-transmitting wheel on a co driving shaft journaled in bearings on t e frame of the machine, so that by moving the cop-holder the wheel carried by the spindle may be thrown into and out of engagement with the driving-wheel on the shaft to stop or start the rotation of the cop. Means is also provided in connection with the movable cop-holder to shift the threadguide away from the cop when the copolder is moved to disengage the two powertransmitting wheels, so that the cop will be accessible to the operator for the purpose of removal or for the purpose of repairing a broken thread and so that the moving threadg uide will not be in contact with the cop referably, also, I combine an automatic stopmotion with the movable cop-holder which Thus any protuberance acts to shift the cop-holder and stop the cop when the thread breaks. v

Herein I have embodied my invention in a winding-machine of that class wherein a mul tiplicity of cops are wound at once, and, as is usual with this class of machine, a multiplicity of thread-guides are carried by a single traverser; but the cop of each thread-guide is carried by an independent cop-holder. When one of the cop-holders is moved to disengage its driving-gears and the thread-guide of that cop is shifted away from the cop by the means above referred to, the movements of the traverser and the thread-guide are not stopped, and in order to conveniently return the reciprocating thread-guide of the stop ed cop to operative position against its cop w ien the said co is started again I provide a movable threa -guide shifter by means of which the operator can, by hand, return the rapidlyreciprocating thread-guide of a sto ped cop to position against said cop when t e latter is started again.

In-the accompanying drawings, Figure 1 is an elevation, partly in section, of a portion of a winding-machine embodying one form of my invention. Fig. 2 is a similar view, but shows some of the arts in different positions. Fig. 3 illustrates t 1e driving mechanism for the traverser and spool-driving shaft hereinafter described. Fig. 4 is a plan view of the cop-holder detached. Fig. 5 is a similar view with a cop in position and showing also the thread-guide and thread-guide shifter hereinafter described. Fig. 6 is a side view, one.

reduced scale, of the mechanism shown in Figs. 1 and 2. Fig: 7 is a detail hereinafter described.

Having reference to the drawings, 1 represents a cross-bar forming part of the frame of the machine, and on this cross-bar is mounted aseries of standards, one of which is shownat 2. On standards 2 is journaled a cop-driving shaft 3, carrying at one end a gear 4, driven through an idler 5 by a gear 6, fast on the main shaft 7 of the machine. Shaft 3 also carries a ear 8, adapted to engage with a gear 9, ast on a spindle 10.

pindle 10 is art of cop-holder 11, mounted to swing on t e axis of a cross-bar 12, supported at its ends by the frame of the machine. Oo holder 11 has fast to it one end of a lateral y-projecting stud 12, on the outer end of which is adjustably fastened a head 13. To head 13 is end of which is acted upon by a spring and the .other end of which bears against a pivoted a lever 14, one

short spindle 16, journaled in head 13. The two sp1ndles'10 and 16 are in axial alinement and are adapted to receive and hold between them a cop-tube or quill 17, onto which the thread is wound. Rotary motion-of shaft 3 is transmitted to cop-tube or quill 17 through gears-8 and 9and spindle 10, and in order to lock the cop-tube or quill to spindle 10, so that it will turn with it, the spindlcis made with teeth 18, which enter the end of the coptube or quill;

The thread that is wound onto cop-tube or quill 17 is laid thereon by a thread-guide 19, carried by a traverser 20, which is journaled in bearings on standards 2 and at one end is fast to a slide 21, mounted in ways 22, fixed to one side of a casing 23 on the frame of the machine. Slide 21 carries a cam-roll 24 in engagement with a cam 25. Cam 25 is fast on a cam-shaft 26, which also carries a gear 27, driven through an idler 28 bya gear 29, fast on main shaft 7. When rotated, cam 25 reciprocates traverser 20 endwise in the usual vents endwise movement As shown in Fig. 7, the threadide 19 is made from a single strip'of metal ent upon itself near its middle, with a loop 19 at one end embracing traverser 20 and clamped thereto to the desired extent by means of screws 19*. The loop 19 is made with a slot 19, into which projects a pin 20, Fig. 6,-

om traverser 20. This construction preof traverser 20 in loop '19, but permits the threaduide to swing resistingly on the traverser w on subjected to pressure toward or from the cop sullicient to overcome the frictional connection between the traverser and thread-guide at loop 19".

In-order to secure the roper relation between the speed of cop-di ivmg shaft 3 and the traverser-actuating cam 25 and to enable variations thereof to be made when the size of thread to be wound varies, so that the helices may be laid attached to t eir shafts,

such changes are to be made. permit, such changes to be made, the studs ca in? idlers 5 and 28 are also adjustable on t e r arcs concenwith change- "The front T-shaped end 36 side by side and close together, the ears 4 and 27 are removably. so that differentsized gears may be substituted therefor when; In order to link 31 is provided with a head 35, which serves to engage frame 33, as described later. Fixed to bracket 33 is a leaf-spring 36, whose free end engages the upper end of frame 33, and said spring serves as a detent to yieldin ly hold frame 33 in its normal position wit an arm 33 against cross-bar 1, as shown in Fi 1, or in its other position with a lug 33 t shown in Fig. 2.

Within frame 33 is ivotally mounted a dog 36, whose inner e'nd 36 is normally just below and out of the path of a swinging arm 37, mounted on a shaft 38, journaled atits ends in bearings on the frame of the machine. An arm 39, fixed to shaft 38, is connected by a link 40 with a crank 41, fast on a continuously-rotated shaft 42, journaled at its ends in bearings on the frame of the machine. The front end 36 of dog 36 is in the form of a T-shaped arm which is somewhat lighter than the rear end 36*, so that normally the front end 36 is held elevated while the rear end 36 is below the path of swinging arm 37. extends under a row of drops 43, and these drops 43 are pivoted on a cross-bar 44, carried by bracket 33. Also each drop has fixed to it an arm 45, provided at its outer end with a threadeye through which a thread passes from the supply to the thread-guide 19, and normally the en agement of the thread with arm 45 holds t e drop in an elevated osition against a stop 46; but if the thread reaks the drop falls and depresses the end 36 of dog 36 and raises the end 36 into thepath'of arm 37.

During the operation of the machine shaft 42 is continuously rotated and acts to continuously vibrate arm 37, so that when the inner end 36 of dog 36 is raised into the path of arm 37 as just described, said dog is struck by said arm and thereby frame 33 is swung on pivot '34 from the position shown in Fi 1 to the position shown in Fig. 2. W en swung in this manner, frame 33 acts, through link 31 and arm 30, to raise cop-holder 1,1 and disengage gear 9 from gear 8, which stops the rotation of spindle 10, while spring 36 serves to hold frame 33 in its forward position, with cop-holder 11 elevated, until returned to its normal osition by the 0 erator. Fixer to stud 12 of t e cop-holder is an arm 47 and when said cop-holder is raised, as above described, the outer end of arm 47 engages thread-guide, 19 and swings it forward on traverser 20 away from cop-tube or uill 17, so as to leave the co accessible to t e operator for the purpose of re airing the broken thread or for the remova of a completed cop.

When the winding is to be resumed, the arts are reset by the o orator depressing a andle 48, projecting f' fom frame 33, and forces said frame back into the position shown in Fig. 1, which allows a spring 11 to return cop-holder 11 to normal osition with gears 8 and 9 in engagement. asmuch as the reciprocations of thread-guide 19 continue uninterru ted, I have herein provided a hand-operate thread-guide shifter 49, pivoted loosely on a bar 50, fixed to the frame of the machine, by means of which the operator can swing the thread-guide 19 back against the cop when handle 48 is depressed to start the winding. This shifter 49 is made with a weighted handle 51, which normally holds the shifterin the position shown in Fig. 1 with a pin 52 on said shifter against a stoppin 53, projecting from bar 50. When the thread-guide 19 is to be returned to its position against the cop, the operator lifts handle 51, which when released automatically returns the shifter to normal position with pin 52 against sto 53.

It will now e apparent that my im roved machine is characterized mainly by t e fact that during the winding operation the threadguide is held against the cop by the frictional connection which connects it with the traverser and that thereby I dispense with the use of a spring or weight continuously holding the thread-guide against the co as has heretofore been practiced, and aYso that the thread-guide recedes from the co as the latter grows, but cannot move in the other direction unless actuated by hand.

The machine above described is es ecially useful in laying square-ended selfinding cops with a relatively quick traverse of the threadguide to the rotation of the cop, helices of the thread being laid at a large angle to the axis of the cop from end to end of the cop. By this mode of operation it is unnecessary to have any headed spools, the cop being built up upon a cylindrical spool or cop shell.

IVhat I claim is 1. In a winding-machine, in combination, a movable cop-holder; cop-actuating means adapted to be thrown into and out of action by the movement of the cop-holder; a traverser; means to actuate the traverser, a

the-

thread-guide frictionally connected with the traverser and movable under pressure of the growing cop'and an arm on the cop-holder for engaging the thread-guide and moving it away from the cop when the cop-holder is moved to throw the cop-actuating means out of action.

2. In a winding-machine, in combination,

a movable cop-holder; cop-actuating means adapted to be thrown into and out of action by movement of the cop-holder a traverser; means to actuate the traverser'; a threadguide frictionally connected with the traverser and movable under pressure of the cop; means to move the thread-guide on the traverser away from the cop when the cop-holder is moved to throw the cop-actuating means out of action, and a movable thread-guide shifter for returning the thread-guide to position against the cop.

3. In a winding-machine, in combination, a thread-guide; a thread-guide traverser means to reciprocate said traverser, means to cause the thread-guide to be reciprocated with the traverser, and means frictionally connecting the thread-guide directly to the traverser so as to yieldingly oppose move ment of the thread-guide on its traverser away from the cop.

4. In a winding-machine, a swinging copholder carrying a cop-s indle; axial driving means for the cop-spindie carried by the copholder; a threadgu1de frictionally engaging a thread-guide traverser; means to actuate the driving means for the cop and the traverser at a predetermined relative rate of movement; a stop-motion operated by the breaking of a thread to disengage the driving means for the oopspindle and its driving means and to lift the reciprocating thread-guide from the surface ofthe cop, all substantially as described.
